thanks for that info,its just i had a 1990 12145 40k before grate tractor was only crash box, slowing down was a bit of problem,but some one had told me that the 8111 and 9111 with the duncan type cab were syncrho, but they also have a neater size cab , is there any other things i should look out for when buying one of these models or is everything much the same as 8011 and 8111 with the bigger cab
